No. 1: Dexter an...We've already examined the most popular puppy names of 2012, but just finding out which names we're most likely to hear at the dog park wasn't quite enough. We wanted to look at which monikers were on the rise, so we dug a little deeper to determine the 10 trendiest names of 2012.

To do so, we hit up Vetstreet's data, which includes information about 1.26 million dogs. We looked at where the names were in 2003 and 2012; those that moved up the most made the list. Of course, some names fell off the list completely in the past decade — Elvis, Ozzie and Cassie among them. Some of these were replaced by newer names like Thor and Athena that, despite a late entry to the Top 100, have become popular enough that they, too, were included.

No. 1: Dexter and Luna Dexter rose in popularity the most of all male dog names, starting at No. 99 in 2003 and landing at No. 25 in 2012.

No. 2: Thor and ...Although Thor didn't even appear on the Most Popular list back in 2003, it climbed to No. 27 in 2012, after making the list for the first time in 2010. Not coincidentally, the movie "Thor" came out in 2011, and the main character in that movie also starred in last year's top film, "The Avengers."

No. 5: Jax and S...At No. 35, Jax isn’t one of the most popular names, but it’s moved up the ranks quickly considering it wasn’t in the Top 100 until 2009. One interesting tidbit: The name Jackson has declined over the past five years, and this is the first time Jax has earned a more popular spot than its longer counterpart.

No. 9: Simba and...Simba, currently No. 53, first became popular during the mid-nineties, thanks to "The Lion King." It dropped out of the Top 100 in 2001, but came back in 2009, seeing a major surge in popularity over the past few years.
